Macrostructure and pollution The macrostructure of bars on the other 1-5-088-77 should not have cracks, utain, tears and segregated clusters. On microtemplate cut from rods are not permitted non-metallic inclusions larger than 0.5 mm in more than two on the bars with diameter up to 50 mm and more than 3 on the bars with the diameter more than 50 mm. of Surface defects on bars (films, layers, bubbles), viewed in microtemplate, not deducing the size of the rod for negative tolerance, acceptance a symptom of are not. The rods allowed for coarse grain rim, the value of which is not limited to, if the mechanical properties of quenched and naturally aged samples cut from the zone of coarse grain rim, will satisfy the requirements of TU 1-5-088-77. At the request of the consumer, coarse bezel may be limited, thus the full value of the rim is determined by agreement of the parties. To control the macrostructure of bars from ø20 mm and higher are cut template from utyaganovo end in the amount of 5% of the party, but not less than three rods. Control of the macrostructure of bars with a diameter less than 20 mm is not possible.
Microstructure The microstructure of hardened bars on the other 1-5-088-77 should not have signs of burnout. Control of the microstructure at high temperatures to produce two samples, cut from two bars from the party.
