FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy and may be used in aerospace engineering, chemical machine building, ship building, automotive industry for making rod-type parts with heads from titanium alloys. After heading, workpiece heat treatment, machining and hardening bolt head filler, thread is cut. Thread is cut on workpiece heated to temperature some 350°C-200°C lower than that of cell formation that occurs in recovery after teat treatment.
EFFECT: ruled out defects in thread cutting, high-quality high-strength bolts of titanium alloys.
