Pseudoelastic effects in CuZn single crystals

摘要: Abstract Mechanical properties associated with pseudoelastic phenomena in CuZn single crystals have been studied and characterized. As a result it is possible to clarify superelastic report on new rubber-like behavior. Two-surface analysis at range of temperatures above Ms demonstrated that the habit plane shape strain direction stress-induced martensitic variant were those lowest Schmid factor 24 variants. The magnitudes measured strains identical resolved theoretical values calculated from phenomenological theory. influence temperature, rate, amount cycling was observed. onset ‘advanced deformation’ (by either nucleation reversible αs martensite or plastic flow) caused modification loops stress-strain curves. ‘Training’ specimens same when cooling near Ms. However, for certain orientations (SIM) further subsequent transformation SIM into (2, 0, 10)9R twin as temperature approached M ƒ . twinned crystal observed behave fashion load below behavior due boundary movement trained its twin. Magnitudes compared predicted values.
