難熔合金
英文
high melting point alloy-
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。But there are some technical difficults for the welding of aluminium alloy such as some broken bits being easily found, a large welding distortion can happen easily, hard to distinguish the difference between the solid metal and liquid metal colour, hard to control the temperature, a lot of air holes can be seen in the welding line and so on
但是鋁合金熔化焊時的技術難點在於：焊接時易引起夾渣，焊接變形大，金屬的固態和液態的色澤不容易區別，焊接操作時控制溫度困難，容易產生氣孔等等。如果焊前清理工作不是很好，檢測氣孔往往超標。Mainly produce the refractory metal materials including wolfram, molybdenum, tantalum, zirconium, niobium, titanium, nickel and the products ; we undertake the manufacture of the compound materials like titanium, nickel, molybdenum, zirconium stainless steel and the vessels, fasteners, titanium basket, titanium panel, etc. our products are extensively applied in many fields like petrol - chemical, chemical fiber, electronics, electric light source, electric vacuum, fertilizer, pharmaceuticals, glass fiber, electrical medium and galvanization, etc

難熔金屬和貴金屬組合的這一層薄膜使刻蝕成為一個艱巨任務。For several years we have invested much funds and manpowers in the area of magnesium alloy melting and casting technologies research. the specialist staff has over - come many difficulties, made many experiments, and has made great achievements
幾年來，我們相繼投入大量的資金人力，將鎂合金的熔煉及定量澆注工藝作月重點課題進行研究，專家小組克服了重重困難，做了大量的實驗，取得了輝煌的成就。Directionally solidified refractory metal matrix eutectic in - suit composites possess excellent mechanical and physical properties such as low density, high enduring temperatures, good room - temperature fracture - toughness and high elevated - temperature strength, therefore are expected to be used as a new type of ultra - high temperature structural materials
定向凝固難熔金屬基共晶自生復合材料由於具有密度低、承溫能力高、室溫斷裂韌性好、高溫強度高和高溫持久壽命長等性能優勢，有望成為新一代航空發動機葉片用超高溫結構材料。Hard alloy, refractory metal, superhard alloy ( diamond ) products, etc
硬質合金、難熔金屬、超硬合金（金剛石）製品等。Inspection and testing procedure for iron, nickel, copper, cobalt and refractory metal base alloy castings
鐵鎳銅鈷和難熔金屬基合金鑄件的檢驗和試驗程序It is difficult to prepare eufe by arc melting for the little difference between the bolting point of eu which is 1596 ? and the melting point of fe which is 1538 ?
Eu的沸點是1596 ， fe的熔點是1536 ，二者非常接近，所以eufe合金的制備比較困難。A superalloy double helix integrated impeller with good performances of dimensional precision, microstructure and mechanics was rapidly manufactured by hpdm ( hybrid plasma deposition & milling ) method proposed by author ' s, laboratory, which synthesized plasma deposition as an additive technology, and milling as a subtractive technique during the processing
