S\u0131cak izostatik presleme (kal\u00e7a), ayn\u0131 anda y\u00fczlerce ila 2000 high aras\u0131nda y\u00fcksek s\u0131cakl\u0131k uygulayarak ve d\u00fczinelerce 200 MPa'ya kadar izostatik presleme yaparak malzemeleri s\u0131k\u0131\u015ft\u0131ran bir malzeme i\u015fleme y\u00f6ntemidir.

S\u0131cak pres kal\u00e7aya \u00e7ok benzer. Frezeleme, d\u00f6vme ve ekstr\u00fczyon da y\u00fcksek s\u0131cakl\u0131k ve y\u00fcksek bas\u0131n\u00e7 i\u00e7in uygundur, ancak s\u0131cak izostatik bas\u0131n\u00e7 i\u00e7in uygun de\u011fildir.<\/p>\n\n\n\n

Kal\u00e7a eklemi ve s\u0131cak presleme aras\u0131ndaki fark<\/strong><\/p>\n\n\n\n

Kal\u00e7a hava bas\u0131nc\u0131 kullanan malzemelere izostatik bas\u0131n\u00e7 uygularken, s\u0131cak bas\u0131n\u00e7 sadece tek eksenli bas\u0131n\u00e7 i\u00e7in ge\u00e7erlidir. Tamamen yetkin bir ekmek\u00e7i<\/p>\n\n\n\n

S\u0131cak izostatik presleme ve s\u0131cak presleme aras\u0131ndaki fark\u0131 net bir \u015fekilde a\u00e7\u0131klamak i\u00e7in, a malzemesine (delikli metal) ve B malzemesine (d\u00fczensiz u\u00e7lu metal) s\u0131cak izostatik presleme veya s\u0131cak preslemenin uyguland\u0131\u011f\u0131 varsay\u0131lmaktad\u0131r.<\/p>\n\n\n\n

Kal\u00e7a eklemi durumunda, \u015eekil 1'de g\u00f6sterildi\u011fi gibi a malzemesi, i\u00e7 g\u00f6zenekler kaybolana ve dif\u00fczyon etkileri nedeniyle birle\u015ftirilene kadar ba\u015flang\u0131\u00e7 \u015feklini korumak i\u00e7in b\u00fcz\u00fclecektir. \u00d6te yandan, e\u015fit olmayan kenara uygulanan e\u015fit bas\u0131n\u00e7 nedeniyle, B malzemesi hi\u00e7 \u015feklini de\u011fi\u015ftirmeyecektir.<\/p>\n\n\n\n

S\u0131cak presleme durumunda, malzeme a, \u015eekil 2'de g\u00f6sterildi\u011fi gibi kal\u00e7a ile ayn\u0131 fenomeni g\u00f6sterecektir. Bununla birlikte, malzeme B sadece d\u00fczensiz \u015fekle sahip olamayacakt\u0131r, \u00e7\u00fcnk\u00fc bas\u0131n\u00e7 sadece y\u00fckseltilmi\u015f par\u00e7aya etki eder.

Kal\u0131p s\u00fcrt\u00fcnmesinin homojen olmamas\u0131 ve deformasyon s\u00fcrecinde s\u0131cakl\u0131k ve boyut s\u0131n\u0131rlamas\u0131 nedeniyle, y\u00fcksek s\u0131cakl\u0131kta b\u00fcy\u00fck \u00fcr\u00fcnler ve kal\u0131plar \u00fcretmek zor olabilir.<\/p>\n\n\n\n

S\u0131cak presleme ile kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda, s\u0131cak izostatik presleme malzeme \u015feklini ba\u015flang\u0131\u00e7 bas\u0131nc\u0131ndan \u00e7ok az farkla sa\u011flayabilir. Bir malzeme, \u015feklini de\u011fi\u015ftirdikten sonra bile ba\u015flang\u0131\u00e7 \u015feklini koruyabilir ve \u00fcr\u00fcn\u00fcn i\u015flenmesi ile nispeten daha az s\u0131n\u0131rl\u0131d\u0131r.
