Master Sintering Surface – A Practical Approach to Its Construction and Utilization for Spark Plasma Sintering Prediction
(International Institute for the Science of Sintering, 2012-08-01)
The sintering is a complex thermally activated process, thus any prediction of sintering behaviour is very welcome not only for industrial purposes. Presented paper shows
the possibility of densification prediction based ...
A Practical Approach for the Calculation of the Activation Energy of the Sintering
(International Institute for the Science of Sintering, 2016-12-15)
Newly developed software for calculation of activation energy (Qs in the following) of
sintering using the Wang and Raj model is presented. To demonstrate the practical potential
of the software and to evaluate the behaviour ...
Influence of Scanning Strategies on Processing of Aluminum Alloy EN AW 2618 Using Selective Laser Melting
(MDPI, 2018-02-14)
This paper deals with various selective laser melting (SLM) processing strategies for aluminum 2618 powder in order to get material densities and properties close to conventionally-produced, high-strength 2618 alloy. To ...
Elastic and Plastic Behavior of the QE22 Magnesium Alloy Reinforced with Short Saffil Fibers and SiC Particles
(MDPI AG, 2018-02-15)
Magnesium alloy QE22 (nominal composition 2 wt % Ag, 2 wt % mixture of rare earth elements, balance Mg) was reinforced with 5 vol % Saffil fibers and 15 vol % SiC particles. The hybrid composite was prepared via the squeeze ...

(International Institute for the Science of Sintering, 2008-01-01)
This article summarizes the usage of high-temperature dilatometry in ceramic processing and powder technology with special attention on the description of the sintering process. A practical method for transformation of ...
Effect of heat treatment on mechanical properties and residual stresses in additively manufactured parts
(Institute of Theoretical and Applied Mechanics of the Czech Academy of Sciences, 2018-05-14)
Heat treatments commonly used for post-processing in additive manufacturing (AM) deal with relieving residual stresses. However, generally these treatments reduce strength properties of material such as yield stress (YS) ...
Influence of Cold-Sprayed, Warm-Sprayed and Plasma Sprayed Layers Deposition on Fatigue Properties of Steel Specimens
(Springer, 2015-03-10)
Titanium powder was deposited onto steel specimens using four thermal spray technologies: plasma spray, low-pressure cold spray, portable cold spray, and warm spray. The specimens were then subjected to strain controlled ...
Influence of Processing Techniques on Microstructure and Mechanical Properties of a Biodegradable Mg-3Zn-2Ca Alloy
(MDPI, 2016-10-28)
New Mg-3Zn-2Ca magnesium alloy was prepared using different processing techniques: gravity casting as well as squeeze casting in liquid and semisolid states. Materials were further thermally treated; thermal treatment of ...
