free cementiteとは 意味・読み方・使い方

As to the method for producing the wire rod, an ingot having the above steel components is hot-rolled to 5 to 16 mm and is subjected to controlled cooling into a wire rod having a pearlitic structure free from the presence of pro- eutectoid cementite.例文帳に追加

並びに、上記鋼成分の鋼塊を熱間圧延で５〜１６mmに熱間圧延し、調整冷却により初析セメンタイトの存在しないパーライト組織の線材とする線材の製造方法。 - 特許庁

The Oldham ring 1 is formed of a carbon-containing iron-based sintered alloy that cementite of 7 to 14% in sectional area ratio of the structure is evenly precipitated in an island form within a base mingled with pearlite and ferrite and free graphite of 0.3 to 1% by weight ratio is evenly dispersed.例文帳に追加

パーライトとフェライトが混在した基地中に、組織の断面積比で７〜１４％のセメンタイトが平均的に島状に析出し、かつ、重量比で０．３〜１％の遊離黒鉛が平均的に分散している炭素含有鉄基焼結合金でオルダムリング１を形成した。 - 特許庁

To obtain high strength spheroidal graphite cast iron as cast which includes a dense structure free from bainite and cementite and having satisfactory machinability, includes high strength satisfying the tensile strength of ≥900 MPa and satisfactory elongation of ≥4% even without the addition of Al, includes excellent machinability, is substitutible for forged steel, cast steel and austemper spheroidal graphite cast iron, and can contribute to the service life and lightening as parts.例文帳に追加

鋳放しで、ベイナイトやセメンタイトのない被削性の良好な緻密な組織からなり、Ａｌの添加なしでも、引張強さ９００ＭＰａ以上の高強度と、４％以上の良好な伸びを有し、優れた被削性を有し、鍛鋼や鋳鋼、オーステンパ球状黒鉛鋳鉄の代替化、部品としての寿命や軽量化に寄与できる鋳放し高強度球状黒鉛鋳鉄を得ることを目的とする。 - 特許庁
