SPT ӘДІСІ БОЙЫНША ШАҒЫН ҮЛГІЛЕРДІ СЫНАУҒА АРНАЛҒАН СЫНАҚ ҚҰРЫЛҒЫСЫН ӘЗІРЛЕУ

Жұмыста шағын үлгілерді SPT әдісімен сынау үшін сынақ құрылғысын әзірлеу және дайындау, сондай-ақ құрастыру нәтижелері келтірілген. Әр түрлі температурада термиялық өңдеуден кейін (шыңдау+жұмсарту) 35Х болат материалын созу және SPT әдістерімен механикалық сынау нәтижелері көрсетілген. Термиялық өңдеу режиміне байланысты 35Х маркалы болаттың беріктік сипаттамаларының өзгеруін бағалау жүргізілді. t/10 әдісі мен созылу сынақтары кезінде алынған әрбір 35X болат үлгісінің аққыштық шегі арасындағы корреляциялық теңдеулер анықталды және алынды.
