Effects of ultrasonic nanocrystal surface modification treatment and subsequent annealing on the microstructure and mechanical properties of rolled AZ31 alloy

Hyun Ji Kim, Sumi Jo, Auezhan T. Amanov, Sang‐Ho Han et autres

This study investigates the variations in the microstructure and mechanical properties of a rolled Mg-3.0Al-0.8Zn-0.3Mn (AZ31, wt.%) alloy caused by ultrasonic nanocrystal surface modification (UNSM) treatment and subsequent annealing. The UNSM-treated material has a gradient microstructure characterized by a nanoscale grain region …

Nanocrystalline Composite Layer Realized by Simple Sintering Without Surface Treatment, Reducing Hydrophilicity and Increasing Thermal Conductivity

Hyun‐Ae Cha, Su‐Jin Ha, Hye‐Jeong Jang, Byeong‐Min Ahn et autres

Abstract The surface treatment for a polymer‐ceramic composite is additionally performed in advanced material industries. To prepare the composite without a surface treatment, the simplest way to manufacture an advanced ceramic‐particle is devised. The method is the formation of a nanocrystalline composite …

Microstructure and Texture Evolutions During Deep Drawing of Mg–Al–Mn Sheets at Elevated Temperatures

Jae‐Hyung Cho, Sang‐Ho Han, Geon Young Lee

Texture and microstructure evolution of ingot and twin-roll casted Mg-Al-Mn magnesium sheets were examined during deep drawing at elevated temperatures. The twin-roll casted sheets possessed smaller grain sizes and weaker basal intensity levels than the ingot-casted sheets. The strength and elongation at …

High Coercivity in MnAl Disc Prepared by Severe Plastic Deformation

Ping Zhan Si, Jung Tae Lim, Jihoon Park, Hak Hyeon Lee et autres

Ping-Zhan Si et al. (article number 1900356) have prepared bulk MnAl nanocrystalline alloy with a highest room-temperature coercivity up to 0.59 T by using a high-pressure torsion process. The severe plastic deformation process decreased the grain size of τ-phase MnAl significantly. As …

High Coercivity in MnAl Disc Prepared by Severe Plastic Deformation

Ping Zhan Si, Jung Tae Lim, Jihoon Park, Hak Hyeon Lee et autres

The low coercivity in MnAl alloys has become a barrier to develop high performance MnAl‐based magnets for more than five decades. Herein, a high room‐temperature coercivity of 0.59 T in MnAl disc is achieved by severe plastic deformation. The grain size of …
