Ti—Ni—Nb三元系相图的信息很有限.1966年, 前苏联学者Pryakhina等人”采用合金法测定 了该三元系相图900c和1000℃含镍量5O (摩尔分数)以上的局部等温截面,指出在所测 区域内共有四个三元化合物.但没有测定低镍 部分.同年,荷兰学者VanVucht【6报导了 ...
The structure of Ti-Nb-B alloys that are cast and annealed at subsolidus temperatures and at 1400°C is experimentally analyzed (x-ray diffraction, metallography, and electron probe microanalysis), and so are temperatures of their phase transformations (differential thermal analysis and pyrometry)....

The phase equilibria of the Ti–Ni–Nb ternary at 9008C have been studied by means of the diffusion couple technique. The 9008C isothermal section of the Ti–Ni–Nb system was plotted based on the present experimental results. Four ternary compounds, X , X , X A B C and X , have be...
Superconducting joints are essential for persistent-mode operation in a superconducting magnet system to produce an ultra-stable magnetic field. Herein, we report rationally designed niobium-titanium (Nb-Ti) superconducting joints and their evaluation re

The 12 single-phase regions include a-Ti solid solution, β-(Ti,Nb) solid solution,Ti2Ni,TiNi,TiNi3,fcc-(Ni) solid solution,Ni3Nb, Ni6Nb7, XA, XB, XC and XD. The ternary compound XB is discovered for the first time. Key words: Ti-Ni-Nb system phase diagram isothermal section ...
Therefore, this study aims to understand the role of Nb in the phase stability of Ti–Ni–Cu–Nb alloys through thermodynamic calculations and microstructural analyses. Based on the binary phase diagram analysis [[17], [18], [19], [20], [21], [22], [23], [24]] and the isomorphous...
因此,用廉价的Cr、Mn及这些元素的合金代替昂贵的Nb、Mo和V元素,设计新牌号钛合金,具有非常重大的实用价值…。Ti.Mn体系是低成本钛合金设计的关键二元系。对该二元系的研究迄今已有五十多年,1953年D.J.Maykuth,H.R.Ogden就报道了第一个实验相图嵋J。近年来随着钛合金的应用日益广大,低成本化成了未来钛合金...
