Effect of Al addition on microstructure of AZ91D [PDF]

, 2014
Casting is a net shape or near net shape forming process so work-hardening will not be applicable for improving properties of magnesium cast alloys.

Effect of Tin, Copper and Boron on the Hot Ductility of 20CrMnTi Steel between 650 °C and 1100 °C

High Temperature Materials and Processes, 2015
The hot ductility of 20CrMnTi steel with x% tin, y% copper and z ppm boron (x = 0, 0.02; y = 0, 0.2; z = 0, 60) was investigated. The results show that tin and copper in 20CrMnTi steel are detrimental to its hot ductility while adding boron can eliminate

Density, Surface Tension, and Viscosity of Liquid Low‐Sulfur Manganese–Boron Steel via Maximum Bubble Pressure and Oscillating Crucible Methods

Steel Research International
In this study, the thermophysical properties of low‐sulfur manganese–boron steel with varying boron and sulfur contents at different temperatures are investigated. Density and surface tension are measured between 1550 and 1650 °C using the maximum bubble

Mechanical properties of Ultrahigh Boron Steels

Advanced Materials, 1995
A fine and stable grain size in steel results in greatly improved mechanical properties. In analogy to the addition of larger quantities of carbon to form ultra‐high carbon steels, the formation of borides in steel through rapid solidification and powder metallurgical techniques leads to the required grain size (see Figure) The materials processing ...

Mechanical Properties of Boronizing Steels as Repercussion of Boron Phases

Materials and Manufacturing Processes, 2009
Results of the boride surface layers investigation, obtained by the torsion and bending methods, point to the better ductility of the mono-phase Fe2B boride layers then the binary-phase FeB + Fe2B boride layers. This is especially outstanding in the case of peaces that are under higher thermal and mechanical load, where the binary-phase layer because ...

Review on the possible tool materials for friction stir welding of steel plates [PDF]

, 2014
The friction stir welding (FSW) process is mainly used in industrial applications for joining low melting temperature materials such as aluminium and magnesium. FSW has many advantages in comparison with conventional fusion arc welding.

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

Advanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.
