μm的碳化物数量最多,在0.6～1.2μm粒径区间的碳化物数量随温度的增高而递减.随着奥氏体化温度的升高,未溶碳化物的面积分数逐渐减少,并得到了未溶碳化物体积分数、面积分数随加热温度变化的拟合方程.","authors":[{"authorName":"占礼春","id":"e0a7b034-e1f1-45f9-98f5-03330366f1a6","originalAuthorName":"占礼春"},{"authorName":"马党参","id":"14a790e4-db0e-41e2-b8fd-7679575f9490","originalAuthorName":"马党参"},{"authorName":"迟宏宵","id":"a5073049-8d04-47cd-b105-f275152f1b0c","originalAuthorName":"迟宏宵"},{"authorName":"周健","id":"8eba6ad0-55d6-4be4-9baa-752a79b356a8","originalAuthorName":"周健"},{"authorName":"蒋业华","id":"d8c7ad7a-5958-4282-b3ef-97c9331f0c69","originalAuthorName":"蒋业华"}],"doi":"","fpage":"29","id":"5fdd787c-e3b2-4801-89d6-07398b10bae5","issue":"10","journal":{"abbrevTitle":"GTYJXB","coverImgSrc":"journal/img/cover/GTYJXB.jpg","id":"30","issnPpub":"1001-0963","publisherId":"GTYJXB","title":"钢铁研究学报"},"keywords":[{"id":"37bb789b-8756-46d1-becb-bd791ff14b41","keyword":"<span
