Maqolada R6AM5 (P6AM5) markali tezkesar po‘latdan tayyorlangan parmalarning yeyilishga bardoshliligini
oshirish maqsadida termik ishlov berishning samarali rejimlari tadqiq etilgan. Unda an’anaviy termik ishlov berish usullari
hamda taklif etilayotgan yangi rejimning po‘lat mikrostrukturasi va mexanik xususiyatlariga ta’siri qiyosiy tahlil qilinadi.
Tadqiqot natijalari shuni ko‘rsatadiki, toblash haroratini 1270–1290 °C gacha oshirish va yakuniy bo‘shatishni 170–370 °C
oralig‘ida amalga oshirish martensit strukturasini boyitish orqali asbobning xizmat muddatini sezilarli darajada uzaytiradi
