Abstract

High temperature creep testing at a very lowload range (< 10 N) on miniaturized specimens has always been a challenge due to inherent design limitation (such as significant preload) of the conventional creep testing machines. In the present study, the challenge was overcome by developing a simple and versatile horizontal creep testing machine to conduct creep tests in the loading range of similar to 6-300 N in tension and in compression. The competence of the in-house-built horizontal creep machine was validated by conducting creep testing on dog-bone shaped sheet specimens of cast Mg-1Sn-1Ca (TX11) Mg-base alloy over a lower stress range of 1.6-5.9 MPa (equivalent load range of 6.4-18.1 N) at 450 degrees C and in the high stress range of 20-80 MPa (equivalent load range of 76-310 N) at 175 degrees C.
