For this purpose, the wires were cooled at temperatures of 850, 950, 1000 degrees Celsius and at different speeds (in the furnace, air, and in front of the fan) and then subjected to the wire stretching process. The resulting wires were aged at a temperature of 200 degrees Celsius and a time of 1 minute. The distribution of hardness in the cross section of the wires before and after the aging process was determined by the microhardness measurement method. The results show that with the increase of sleeve temperature, the increase of hardness with sensitivity to strain aging increases and with the increase of cooling rate, the increase of hardness with sensitivity to strain aging decreases. In addition, before the static strain aging process, the hardness distribution in the cross-section of the wire from the center to the surface is upward, and after aging, the hardness distribution is downward. Also, the increase in hardness due to aging is decreasing from the center to the surface.<\/strong><\/span><\/p>\n<h2 style=\"text-align: right;\"><span style=\"color:

strain <a href=\"https:\/\/civilica.com\/doc\/202608\/\">aging<\/a> in steel are carbon and nitrogen dissolved in the field. With the increase of soluble interstitial elements in the field, their influence on the dislocations becomes faster, and as a result, more changes in mechanical properties are observed in shorter times, and the sensitivity to strain aging increases. Due to the increase in the amount of nitrogen and carbon dissolved in steel due to the increase in the temperature of the sleeve with the temperature after the final stage of rolling at a constant cooling rate, the sensitivity to strain aging of the steel increases. On the other hand, as the austenite temperature of coarser austenite grains increases, the grain boundaries decrease and the rate of penetration of interstitial elements (through the boundaries) also decreases and the sensitivity to strain aging decreases. Slow hardening rates of steel from the austenitic temperature help to form carbide and nitride deposits, as a result of which the dissolved carbon and nitrogen elements in the field are reduced and the susceptibility to strain aging is reduced. The cooling rate from the austenitic temperature can increase the sensitivity to strain for two reasons. Increasing the amount of dissolved nitrogen and carbon in steel, increasing the rate of germination of ferrite from austenite and creating a fine grain structure, as a result of which the area of the grain boundary increases and the rate of penetration of interstitial elements through the boundaries increases, and the sensitivity to strain aging increases.<\/strong><\/span><\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-kubc8-2613bccde65349a17754540a187f25c8\">\n.flex_column.av-kubc8-2613bccde65349a17754540a187f25c8{\n-webkit-border-radius:0px 0px 0px 0px;\n-moz-border-radius:0px 0px 0px 0px;\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-kubc8-2613bccde65349a17754540a187f25c8 av_one_half  avia-builder-el-3  el_after_av_one_full  el_before_av_one_half  first flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-l56lncfi-7a44e564de850ec9eb6ecf5b27a1de17 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><span dir=\"RTL\" lang=\"AR-SA\" style=\"font-size: 16pt; font-family: 'Times New Roman';\">Click on the link to read more.<\/span><\/p>\n<\/div><\/section><\/div><\/p>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4vhnq0-47b59b63da73f966ff9752c85f86627f\">\n.flex_column.av-4vhnq0-47b59b63da73f966ff9752c85f86627f{\n-webkit-border-radius:0px 0px 0px 0px;\n-moz-border-radius:0px 0px 0px 0px;\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-4vhnq0-47b59b63da73f966ff9752c85f86627f av_one_half  avia-builder-el-5  el_after_av_one_half  avia-builder-el-last  flex_column_div av-zero-column-padding  column-top-margin'     ><div  class='avia-button-wrap av-328rjc-67ad59d0b8b92a449c0beed12b88a39d-wrap avia-button-center  avia-builder-el-6  avia-builder-el-no-sibling '><a href='https:\/\/civilica.com\/doc\/202608\/' class='avia-button av-328rjc-67ad59d0b8b92a449c0beed12b88a39d avia-icon_select-yes-right-icon avia-size-small avia-position-center avia-color-theme-color' target=\"_blank\" rel=\"noopener noreferrer\"><span class='avia_iconbox_title' >Read more<\/span><span class='avia_button_icon avia_button_icon_right' aria-hidden='true' data-av_icon='\ue830' data-av_iconfont='entypo-fontello'><\/span><\/a><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0},"categories":[18,16],"tags":[119],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.8 -
