Abstract

The present work examines how the characteristics of the large thermal-compressive response of a 20 vol. % NiTi fiber 6082-T0 composite change with variations in the value of maximum tensile strain imposed during a preceding room temperature tensile process. We observe that the self thermal compression process is shifted to higher temperatures with increasing maximum room temperature tensile strain, and that the maximal thermal compression versus temperature slope becomes larger as the maximum tensile strain is increased from 4 to 6% and then becomes smaller as the maximum tensile strain is further increased to 7%.
