Liquid metal embrittlementとは 意味・読み方・使い方

To provide a steel sheet for hot pressing, which has superior oxidation resistance by sufficiently preventing generation of scales or ZnO during hot pressing, and also which has superior liquid metal brittleness resistance without causing the liquid metal embrittlement cracking due to elements contained in a plating layer, and to provide a method of producing a hot-pressed member using the steel sheet.例文帳に追加

熱間プレス時にスケールやZnOの生成が十分に抑制されて耐酸化性に優れるとともに、めっき層中の元素に起因する液体金属脆性割れが起こることのない耐液体金属脆性に優れた熱間プレス用鋼板およびそれを用いた熱間プレス部材の製造方法を提供する。 - 特許庁

To provide a flux-cored wire for gas shielded arc welding, when a hydrochloric acid and sulfuric acid dewpoint corrosion resistant steel is subjected to gas shielded arc welding, capable of obtaining a weld metal having excellent sulfuric acid corrosion resistance and hydrochloric acid corrosion resistance and also having excellent strength and impact toughness while suppressing occurrence in the liquid metal embrittlement cracks of the weld metal caused by Cu and Sb as low melting point components.例文帳に追加

耐塩酸及び耐硫酸露点腐食鋼をガスシールドアーク溶接した際に、低融点成分であるＣｕ及びＳｂに起因する溶接金属の液体金属脆化割れ発生を抑制しつつ、耐硫酸腐食性と耐塩酸腐食性とが共に優れ、かつ強度及び衝撃靱性に優れた溶接金属が得られるガスシールドアーク溶接用フラックス入りワイヤを提供する。 - 特許庁

To provide a zinc alloy plated steel having excellent weldability with which, when welding the zinc alloy plated steel having a tensile strength of base material not lower than 490 MPa class strength level and a thickness of 0.8 to 9 mm by various methods, liquid-metal embrittlement cracking occurring due to zinc alloy plating particularly in a weld heat-affected zone can be stably suppressed and high reliability welded joints can be obtained.例文帳に追加

母材の引張り強さが４９０ＭＰａ級以上の強度レベルで、板厚が０．８〜９ｍｍの亜鉛系合金めっき鋼材を種々の方法で溶接する際に、特に溶接熱影響部で亜鉛系合金めっきに起因して発生する液体金属脆化割れを安定して抑制でき、信頼性の高い溶接継手を得るための溶接性に優れた亜鉛系合金めっき鋼材を提供する。 - 特許庁

On the premise of addition of Ti, the liquid metal embrittlement resistant characteristics can be improved, even in the high strength steel sheet having ≥590 MPa by adding fine quantity of B and one or more elements among Nb, Mo and Cr and further, since the martensitic structure can easily be obtained by adding Cu and Ni, the strength of ≥590 MPa is stably obtained.例文帳に追加

Ｔｉ添加を前提として、微量のＢやＮｂ，Ｍｏ，Ｃｒの一種または２種以上を添加することにより、５９０ＭＰａ以上の高強度鋼板においても耐溶融金属脆化特性が改善でき、更に、Ｃｕ，Ｎｉを添加することにより容易にマルテンサイト組織が得られるようになるため、安定して５９０ＭＰａ以上の強度が得られる。 - 特許庁
