cannot take place is close to 100 u00b0 c solution treated sheets of alloy 42 were cold rolled to thickness with 10 and 20 reduction the pseudo elastic recovery strain by bend tests of samples with and without cold work are plotted in fig1 it can be seen that pseudo elastic strain recovery decreases only slightly as a result of increasing amount of cold work indicating that pseudo elasticity in this alloy is not significantly affected by cold deformation up to 20 the new alloy x42025 based on the composition of alloy 42 was melted and processed to wires of 0 061 u2033 and 0 016 u2033 diameter the wet chemical analysis showed that the alloy has a chemical composition of ti 11 14 wt mo 2 95 wt al 1 88 wt v 3 99 wt nb the tensile loading to 4 strain followed by unloading to zero stress curves of alloy x42025 are shown in fig1 again the alloy exhibits distinct pe between u2212 25 u00b0 c and 50 u00b0 c comparing the chemical compositions of alloys 42 and x42025 it is noted that even though the composition of molybdenum in x42025 is almost one percent higher than that of alloy 42 both exhibit significant pe in a quite similar temperature range since the martensite transformation temperatures are.
