Thin coatings on metallic substrates are extensively used in mechanical, aerospace, microelectronic, optical, and medical applications. Coatings affect the surface properties of the system, while bulk properties and strength primarily depend on the substrate. In coated components subjected to thermal cycling, differences in physical properties and chemical nature between constituent parts of co...

In this study, we demonstrate an effective approach based on a simple processing method to improve the thermomechanical properties of graphene polymer composites (GPCs). Edge-selectively functionalized graphene (EFG) was successfully obtained through simple ball milling of natural graphite in the presence of dry ice, which acted as the source of carboxyl functional groups that were attached to ...

Experimental investigations of the thermomechanical processing (TMP) metals clearly demonstrate that technological process-tuning parameters have a great influence on evolution both microstructure and texture, which determine chemical, physical, mechanical properties [...]

In this paper, an advanced thermo-mechanical treatment was conducted on AISI 316 austenitic stainless steel. At first, three samples were rolled at the ambient temperature, the temperature of -20 ºC (dry ice and ethanol) and -196 ºC (liquid nitrogen). Then, the samples were annealed at 800 ºC in the time range of 1 to 15 minutes. In each step, the microhardness values of the samples were measur...

A repeated thermomechanical treatment (RTMT) was adopted to control the microstructure of a glass-balloon-dispersed aluminum alloy (AC3A) composite. The RTMT, which involves the repetition of a multi-step process and followed by heat treatment, was applied to a cast plate of the composite. The composite was successfully worked into a rod or sheet by either swaging or flat rolling. The porous gl...

Au-Sn solid–liquid interdiffusion (SLID) bonding is a novel and promising interconnect technology for high-temperature applications. This article gives a review over previously published work on Au-Sn SLID bonding. An overview of the crystal phases and the thermomechanical properties of the Au-Sn phases relevant for Au-Sn SLID bonding is given. A summary of the bonding conditions used during Au...

Inequalities in thermomechanical properties of materials at interfaces of a modern package lead to a rise in periodic stresses during normal operation, making these sites crucial to the integrity of the entire product. Proper lifetime analysis for highly miniaturized interconnects is a real challenge. In addition, broad application of 100% quality standards in various industries has caused a ra...

First, I give a short description of the history of the interpretation of the second law of thermodynamics as a restriction on the kind of material properties that physical systems occurring in nature can have. Second, I describe the desirability of developing a framework, using the concept of a state of a material element, for developing a general thermomechanical theory of simple materials.Th...
