When WC grains in cemented carbide are less than 0.5 \u03bc m, the finer the grains are, the fewer the defects are, and the higher the bending strength and hardness are The particle size of WC powder used to produce ultrafine cemented carbide is much smaller than that of WC powder used in general cemented carbide. The WC powder has high activity and is easy to cause grain growth in the sintering process, which is one of the crack sources. At present, there are two main methods to control the grain size: First, a new sintering process is adopted. The results show that the densification of dozens of nano WC…<\/p>","protected":false},"author":2,"featured_media":19477,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[79],"tags":[],"class_list":["post-18365","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-materials-weekly"],"jetpack_featured_media_url":"https:\/\/www.meetyoucarbide.com\/wp-content\/uploads\/2019\/11\/1-2.png","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/18365","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/comments?post=18365"}],"version-history":[{"count":0,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/18365\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media\/19477"}],"wp:attachment":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media?parent=18365"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/categories?post=18365"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/tags?post=18365"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
