ENGINEERING RESEARCH INSTITUTE * UNIVERSITY OF MICHIGAN BIMONTHLY PROGRESS REPORT NO. XV THERMAL.-SHOCK INVESTIGATION OBJECT The object of this research is to evaluate optimum design of test specimens and to develop criteria which will permit correlation of thermalshock data with performance of the material in the form of turbine buckets SIWMMARY.1 I All testing rigs are now in full automatic operation. High-u temperature tests have been performed on S-.816 wrought alloy and on N-155 wrought alloy. S-816 shows little change in thermal-shock resistance when the temperature is elevated from 18000F to 1900 and 2000~F. N-155 alloy also shows only a slight decrease in thermal-shock resistance at 1900 and 2000~F as contrasted to -its properties at 1800~F. Photomicrographs of HS-21 alloys, made to check the effects of heat treatment at 1350~F for 51 hours, verified the published results of the manufacturer. Hardness tests of the same material also matched the published figures. Tests are being made on the following alloys: Inconel~ Waspalloy, M-252, and Hastelloy C. Partial data are included in this report, Construction of apparatus to permit testing of Inconel in an inert atmosphere (helium) is progressing Previously reported data on Inconel tests at 1900 and 2000~F were inconclusive pending further examination for presence I

ENGINEERING RESEARCH INSTITUTE * UNIVERSITY OF MICHIGAN of cracks. This examination has shown that no cracks were developed in the base metalt but only in the heavy surface scale. INTRODUCTION Final details involved in construction of the test apparatus were completed during the middle of December~ 1953. This work included soundproof boxes camera mountings, reproducibility tests, and installation of calibration equipment. Since January- 1 954-, all the test rigs have been in full automatic operation. Certain operation must still be performed manually) however. The most important of these is the periodic resetting of the variac autotransoformers to accommodate changes in the line voltage. Such voltage changes occur at about 8 a.m., 12 im., and 5 pm. each week day) but seldom over the week end. The voltage change is usually only a few volts, but it produces a change of several seconds in the heating time of the specimen cycle. In order to maintain the cycle as nearly uniform as possible, regular checks are made of the apparatus at the times when changes are known to occur. In addition to the line-voltage fluctuations, a change in the resistance of the test specimen develops simultaneously with the developent of a crack. This resistance change also serves to change the heating time of the test cycle) since the place at which the crack is developing soon becomes a hotter spot than the rest of the piece. Such cyclic variations also require regulating the variacs manually. Automatic camera equipment is used to monitor the development and progress of cracks during week*-end tests or hightperature tests. In most progreS'S S vc -.1. ~~~~~~~In m os t of the tests at 1900 and 20000F the life of the specimen is less thn a thousand cycles. To determine when a crack starts and to follow its progress across the face of the test piece would require almost constant attention. For such tests the automatic recording devices are used, but for the lowers temperature longer-time tests, a visual inspection is made at periodic intervals. This has proven to be close enough in the past, and results in a large saving in film costs on tests which last several thousands of cycles. Temperature calibration of each test rig must still be performed manually at the beginning and the end of each test run with a special test piece in which a thermocouple has been imbedded. The information is read from a separate temperature recorder which is not connected to any of the 2

- ENGINEERING RESEARCH INSTITUTE * UNIVERSITY OF MICHIGAN radiation pyrometer temperature controllers in the test rigs. Thus, a separate check -is maintained of the amount of drift which has-taen place in- the radiation-measuring devices. Thus far the operation of the test rigs has been trouble-free. It was expected that certain bothersome failures might occur in a de-vice as complex as the test apparatus has become, but the present design has proven to be very satisfactory. About the only important improvement which seems in order is to axrange some sort of feedback mechanism between the heating timers- and the variacs; so that the heting time can -automatically be kept at a constant value. Previous work-on Inconel has shown that this material is subject to severe surface corrosion at elevated temperatures. When tests were run at temperatures of 1900 and 2000QF it became very difficult to tell whether any cracks had. developed in the body of a test piece because of the presence of very heavy surface Scle. Several tests were reported in Progress Report XIV as being subject to examination subsequent to the test. Although it appeared at the time of the test that there were numerous large and rapidly progressing cracks in the material an optical check at high magnification failed to find evidence of any cracks other than those in the surface scale. Once the scale was removed. the surface appeared to be undamaged. In order to eliminate the surface oxidation on Inconel,- a series of tests are to be run with helium substituted for the compressed air pres~.s ently being used, In this inert atmosphere any surface scaling effects should be reduced to a mininmumtu: thus permitting a more accurate determination -of the crack development and progress Certain changes are to be made in the air circuitof the test rigs to permit -the introduc tion of helium into one of the sets of nozzles. These changes require the use of special manifolding equipments which is now under construction. DISCUSSION Progress Report XIV contains a discussion of the results of tests performed. on HS:-21 in an effort to determine the effects of change in ducs tility on the thermal-*shock properties of that material. After the results were reported there arose a question as to whether the heat treatment of 51 hours -at 1550F had actually accomplished the desired effect. To answer this question a set of photomicrographs were made of the material in both the as-east and the heat-treated condition (Figs. 1 through 4). They show that the specified heat treatment accomplished the same results as those published by the manufacturer. 3

ENGINEERING RESEARCH INSTITUTE * UNIVERSITY OF MICHIGAN Tests have been run on six different materials in the period from December t2~ 19552 to February 12, 1-954. These materials are Waspalloy Inconel, N-155, S 816 M-252 ad Hastelloy C.- None of the series o tests are complete as of the Igddle of February; therefore only partially. complete data are being reported at this time. For Waspalloy the data are as follows: Specimen No. Cyc le No. of Cycles Type of Failure A3 1 A3"5 A5.6 A3-4 A35.9 A3-8 A3-9 16oo00/5 16oo00/5 1800/5 18oo00/5 1800/5 1700/5 1700/5 1700/5 1650/5 10t050 15, 0)i8 1, 789 6135 784 742 879 1,690 C 'C C C C.C C C C Statistical analysis of these data shows that -the number of cycles to failure for l600*F is above 10000 cycles. The average cycles to failure -re 980 cycles for 1700*F and 1062 cycles for 1800QF with probable errors of 189 and 405 cycles respectively. The data indicate that there is a very large drop in thermal:shock resistance of Waspalloy above 1600*F but that it is still of the order of 1000 Cycles. This is ten times the arbitrary standard of 100 cycles assumed for normal service conditions. Data obtained. for three tests of lHastelloy C are: Specimen No. Cycle No. of Cycles Type of-Failure C-1 C-2 c~5 1600/5 1600oo/5 16o00/5 4,_618 2,.240 7,546 C C On the basis of these observations, the average thermal.-shock resistance of this alloy at '1600F is 48o01 cycles with a probable error of 1557 cycles.

At 17000F the value became 2107 cycles with 'a probable error of 312 cycles. This would indicate a moderate loss of thermalishock resistance between 1600 -and l700uFe Tbut in both cases the value is several times the arbitrary 100 -cycle value. The data for 1800'F is too sparse to be reliable. 5

ENGINEERING RESEARCH INSTITUTE * UNIVERSITY OF MICHIGAN - These data show that for S*816 alloy the average thermaa1:shock:cycles to failure at 20000F is 891 cycles with a probable error of 63 cycles. At 1900~F the average value is l170 cycles, plus or 'minus 101 cycles. For N155 alloy at -1900~F the average thermal-*shock cycles to failure is 1496* 22 cycles At 2000OF the data appear to be inconclusive, but a rough estimate places the thermal-shock resistance at about 1000 cycles. At high temperatures these two materials show more uniform results tha any other materials tested as indicated by the small probable.-error values. Results of all data on N*155 and S..816 are shown in Figs. 5 and 6.
