A Cr3C2-VC composite grain growth inhibitor is combined with a CoNiFe multi-principal-element alloy binder to yield ultrafine-grained WC-6MPEA-Cr3C2-VC with improved stability and mechanical properties. Composite inhibition and MPEA binder synergy refine WC grains to 0.28 μm, suppress the FCC-to-HCP transformation, and promote crack deflection and localized transgranular fracture, delivering 93.7 HRA, 1974 HV30, and 3016 MPa.","cbCaiqT0NZJtyFM1","https://ap.wps.com/l/cbCaiqT0NZJtyFM1","pdf",4868647,4,1,19,"English","en","# Abstract\n# Key words\n# Introduction\n## Background and definitions of ultrafine-grained cemented carbides\n## Limitations of conventional WC–Co and the need for low-binder systems\n## Role of MPEA binders and challenges for ultrafine-grained WC\n## Need for grain growth inhibitors and motivation for composite Cr3C2–VC","[{\"question\":\"Which mechanical property improvements are reported for the optimized WC-6MPEA-Cr3C2-VC sample?\",\"answer\":\"The optimized sample achieves Rockwell hardness of 93.7 HRA, Vickers hardness of 1974 HV30, and transverse rupture strength of 3016 MPa, attributed to a refined WC microstructure and stable two-phase binder behavior.\"}]",1780693420,48,{"code":4,"msg":29,"data":30},"ok",{"site_id":31,"language":23,"slug":32,"title":13,"keywords":33,"description":14,"schema_data":34,"social_meta":77,"head_meta":79,"extra_data":81,"updated_unix":26},105,"microstructure-and-mechanical-properties-of-ultrafine-grained-wc-conife-cr3c2-vc-cemented-carbides-with-a-multi-principal-element-alloy-binder","",{"@graph":35,"@context":76},[36,52,67],{"@type":37,"itemListElement":38},"BreadcrumbList",[39,43,47,50],{"item":40,"name":41,"@type":42,"position":20},"https://docshare.wps.com","Home","ListItem",{"item":44,"name":45,"@type":42,"position":46},"https://docshare.wps.com/document/","Document",2,{"item":48,"name":12,"@type":42,"position":49},"https://docshare.wps.com/document/research-report/",3,{"item":51,"name":13,"@type":42,"position":19},"https://docshare.wps.com/document/microstructure-and-mechanical-properties-of-ultrafine-grained-wc-conife-cr3c2-vc-cemented-carbides-with-a-multi-principal-element-alloy-binder/32055/",{"url":51,"name":13,"@type":53,"author":54,"headline":13,"publisher":56,"fileFormat":59,"description":14,"dateModified":60,"datePublished":61,"encodingFormat":59,"isAccessibleForFree":62,"interactionStatistic":63},"DigitalDocument",{"name":9,"@type":55},"Person",{"url":40,"name":57,"@type":58},"DocShare","Organization","application/pdf","2026-06-13","2026-06-05",true,{"@type":64,"interactionType":65,"userInteractionCount":19},"InteractionCounter",{"@type":66},"ViewAction",{"@type":68,"mainEntity":69},"FAQPage",[70],{"name":71,"@type":72,"acceptedAnswer":73},"Which mechanical property improvements are reported for the optimized WC-6MPEA-Cr3C2-VC sample?","Question",{"text":74,"@type":75},"The optimized sample achieves Rockwell hardness of 93.7 HRA, Vickers hardness of 1974 HV30, and transverse rupture strength of 3016 MPa, attributed to a refined WC microstructure and stable two-phase binder behavior.","Answer","https://schema.org",{"og:url":51,"og:type":78,"og:title":13,"og:site_name":57,"og:description":14},"article",{"robots":80,"canonical":51},"index,follow",{"doc_id":7,"site_id":31}]
