Influence of cold expansion of holes on crack initiation and growth in aluminum alloys [PDF]

, 2014
Досліджено вплив відносного натягу дорнування отворів на період зародження та швидкість поширення втомних тріщин в алюмінієвому сплаві Д16чТ. Виявлено, що незалежно від натягу дорнування (1–3%) тріщина зароджувалася від кромок отвору з боку входження ...
