Young's modulus of typical Ti-V, Ti-Mo and Ti-Nb binary alloys with similar phase diagrams was measured as a function of composition along with microstructural observations. Young's modulus fo beta Ti binary alloys solution treated and quenched exhibits minimum value of 72 GPa for Ti- 26%V, 85 GPa for Ti-15%Mo, and 62 GPa for Ti-42%Nb. Transmissioin electron microscopy indicates that athermal omega transformation is induced in unstable beta alloys, and the minimum in Young's modulus appears at a composition where athermal omega transformation is suppressed by increasing alloying content. Based on the obtained results on the binary alloys, ternary Sn additions were investigated to lower Young's modulus by suppressing omega transformation. It is found that the optimization of composition in Ti-Nb-Sn alloys decreases Young's modulus to about 50 GPa under a soution treated - Current Status of Titanium Industry in Japan 일본의 티타늄산업구조의 특징, 일본의 티타늄 수요, 용도의 특징, 금후 의 과제와 전망 * 관리자님에 의해서 게시물 복사되었습니다 (2005-10-25 16:32)
