SOLUTION STRENGTHENING AND AGE HARDENING CAPABILITY OF Al-Mg-Mn ALLOYS WITH SMALL ADDITIONS OF Cu
Nine Al-(1-3)Mg-(0-0.4)Cu-0.15Si-0.25Mn (in wt%) alloys with potential applications in both packaging and automotive industries have been investigated. Tensile testing showed that solution strengthening is in good approximation linearly proportional to the Mg content. Mechanical testing and microstructural examinations of aged samples indicate that Mg2Si phase precipitates contribute to age har...

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

متن کاملMICROSTRUCURE AND STRENGTHENING OF Al-Li-Cu-Mg ALLOYS
A detailed quantitative model for the strengthening of monolithic alloys and composites due to precipitation strengthening, solution strengthening, grain and subgrain strengthening, strengthening by dislocations and load transfer to ceramic inclusions is presented. The model includes a newly derived description of the effect of a precipitate free zone (PFZ) around the reinforcing phase incorpor...
متن کاملAl - Mg - Cu based alloys and pure Al processed by high pressure torsion : the influence of alloying additions on strengthening
The influence of alloying additions on strengthening of high pressure torsion (HPT) processed alloys was investigated using commercially pure Al (Al-1050 alloy) and five Al-(1-3)Mg-(0-4)Cu alloys (in wt%). Microhardness was measured on cross sections. For Al-1050 the microhardness reaches a peak at an effective strain of about 3 and subsequently decreases. The microhardness of Al-Mg-Cu alloys i...
