TL;DR: In this paper, three different grain structures of low-carbon medium-manganese steel were prepared through appropriate controlled rolling process, and the laminated microstructure with a strong rolling direction fiber texture was characterized by ultra-fine elongated ferrite, retained austenite and martensite phase arranged alternately along the RD.

TL;DR: In this article, a novel process of planting carbon nanotubes (CNTs) within spherical Ti-6Al-4V powder to fabricate a CNTs/Ti-6al-4v composite powder was developed, which addressed the issues of spherical morphology maintaining and homogenous dispersion of CNT, and exhibited good printability.

TL;DR: The formation of a bioactive nanoscale apatite, cell–nanotube interactions as imaged via electron microscopy, higher expression of proteins (actin, vinculin, fibronectin, and alkaline phosphatase (ALP)), and calcium content points toward the determining role of anodized mesh structure in modulating osteoblasts functions.

TL;DR: The biological response of electron beam melted low modulus Ti2448 alloy porous mesh structure through the elucidation of bioactivity and osteoblast functions is explored and the combination of unique surface chemistry and interconnected porous architecture provided the desired pathway for supply of nutrients and oxygen to cells and a favorable osteogenic micro-environment for incorporation of osteoblasts.

TL;DR: In this article, a novel TMCP involving ultra-fast cooling (UFC) was used to process microalloyed 560 MPa (X80) strip with critical thickness of 22mm, and the microstructure and mechanical properties including tensile, Charpy v-notch impact toughness, and drop weight tear test (DWTT) properties were studied.
