相变诱发塑性不锈钢是一种新型的超高强度不锈钢。它籍助相变诱发塑性(TRIP)的机制,克服了高强度和超高强度钢随着强度的提高而塑性降低的矛盾。而使钢在高的强度水平下具有独特的塑韧性。 本文中的25Cr9Ni8Mo4Si2不锈钢通过合适的温拉丝工艺之后,具有明显的相变诱发塑性的效应,钢丝性能可达:σ_b≥175-180公斤/毫米~2δ=18-32％,比同等强度的18-8冷拉不锈钢丝的塑性约提高6～8倍。本钢丝可用于制造外科医用缝针、特殊用途的超高强度钢丝(如高压容器用的缠绕丝)和钢丝绳以及化工用的弹簧等。
Phase change induced plasticity stainless steel is a new type of ultra-high strength stainless steel. It is aided by the mechanism of phase change induced plasticity (TRIP), to overcome the high strength and high strength steel with increasing strength and plasticity of the contradiction. Leaving the steel with a unique plasticity and toughness at high strength levels. In this paper, 25Cr9Ni8Mo4Si2 stainless steel through a suitable temperature drawing process, the obvious phase transition induced plasticity effect, the wire performance up: σ_b ≥ 175-180 kg / mm ~ 2δ = 18-32%, than the same strength 18- 8 cold-drawn stainless steel wire plastic about 6 to 8 times. The wire can be used to make surgical stitches, special purpose ultra-high-strength steel wire (such as high voltage container with winding wire) and wire rope and chemical springs.
