Abstract
Systematic studies were carried out on the compressive effects of Ta single crystals grown by electron beam melting methods. Stress-strain curves of various Ta single crystals were obtained in order to clarify the effect of compressive deformation. According to the stress-strain curves and surface observation, the following results were obtained.
It was cleared that the work hardening effect of Ta single crystals, examined by using compression tests, was determined to be, smaller in the order of directions <100>, <111>, and <110>, and also smaller in the order from <111> to <110>, and from <100> to <110>, as it was the the same as the Fe single crystals.
