金相可焊性 的英文怎麼說
中文拼音 [jīnxiāngkěhànxìng]
金相可焊性
英文
metallurgical weldability-
It is a dozen metals in one ; now almost diamond - hard - - and again almost as soft as copper ; here brittle as glass ? there malleable1o as silver ; now welding quite readily - - again, very difficult to weld ; melting rather easily - - at other times difficult to diffuse ; usually very magnetic - - and : again almost non - magnetic ; an excellent conductor of heat and electricity - - and at times stubbornly resistant to both
鐵將十多種金屬特性合而為一：時而幾乎堅硬如金剛石，時而又柔軟如銅；此處易碎如玻璃，彼處又可展延如銀；時而很容易焊接，時而又很難焊合；有時相當易熔，有時又極難擴散；通常情況下富有磁性，但有時又幾乎磁性全無；本是熱和電的優良導體，但有時卻頑強地抗拒二者。The purpose of the paper is to search the feasibility of the ecletron - beam weld of ti3al intermetallics and tc11 ( a + b ) two phase titanium alloy, and the influence to weld microstructure and properties of the hot deform and heat treatments
本文的目的是探索ti _ 3al金屬化合物tac - 1b合金與tc11兩相鈦合金電子束焊、熱模鍛及熱處理的可行性，並研究焊后熱加工變形與熱處理對組織與性能的影響。In the five key factors of solder ball alloy, solder paste alloy, peak temperature, the time above liquidus and soldering environment, the fore four factors are more important than soldering environment to the solder joints reliability
在焊球合金、焊料合金、峰值溫度、液相線以上時間和焊接環境五個關鍵因素中，前四項對焊點可靠性比較重要，焊接環境對焊點可靠性的影響不很顯著。
