style=\"color:red\">30MnSi</span>母材为研究对象,借助金相光学显微镜、酸洗低倍、显微硬度计、扫描电子显微镜等分析手段,对<span style=\"color:red\">PC</span><span style=\"color:red\">钢</span><span style=\"color:red\">棒</span>延迟断裂现象进行深入细致的研究。通过大量的试验数据分析发现,引起<span style=\"color:red\">PC</span><span style=\"color:red\">钢</span><span style=\"color:red\">棒</span>延迟断裂的原因主要有<span style=\"color:red\">钢</span><span style=\"color:red\">棒</span>内部夹杂、表面缺陷及<span style=\"color:red\">热处理工艺</span>等几个方面,并通过延迟断裂的形成原因,有针对性的作出了相应的预防措施,有效的解决了<span style=\"color:red\">PC</span><span style=\"color:red\">钢</span><span style=\"color:red\">棒</span>延迟断裂问题。","authors":[{"authorName":"何力国","id":"459e59b7-77f3-4aec-9fdc-39aa6f604bf6","originalAuthorName":"何力国"},{"authorName":"王刚","id":"befc1d09-bc10-44e4-a488-3d9fe900d8c0","originalAuthorName":"王刚"},{"authorName":"薛俊峰","id":"ef1a81a5-8c83-43dc-955c-ab9ac290fdea","originalAuthorName":"薛俊峰"},{"authorName":"李明贤","id":"6f08212d-4408-438d-9424-74e29725c9d8","originalAuthorName":"李明贤"}],"doi":"","fpage":"46","id":"6d1d3941-b6e1-45de-9c13-ea2ff7e7725a","issue":"6","journal":{"abbrevTitle":"WLCS","coverImgSrc":"journal/img/cover/WLCS.jpg","id":"64","issnPpub":"1001-0777","publisherId":"WLCS","title":"物理测试"},"keywords":[{"id":"df8a9f49-8269-4403-9ea1-b4f72132a4fc","keyword":"<span
