Effect of Heat Treatment on the Microstructure and Hardness of Ni-Based Alloy 718 in a Variable Thickness Geometry Deposited by Powder Fed Directed Energy Deposition
(MDPI, 2022)
Feature addition to existing parts is a trending application for Directed Energy Deposition (DED) and can be used to add complex geometry features to basic forged geometries with the aim to reduce and simplify the number ...
Review of Intermediate Strain Rate Testing Devices
(MDPI, 2020-07-05)
Materials undergo various loading conditions during different manufacturing processes, including varying strain rates and temperatures. Research has shown that the deformation of metals and alloys during manufacturing ...
Laser Dissimilar Joining of Al7075T6 with Glass-Fiber-Reinforced Polyamide Composite
(MDPI, 2020-01-22)
Dissimilar joining between metal and composite sheets is usually carried out by mechanical or adhesive joining. Laser dissimilar joining between metal and composite sheets could be an alternative to these methods, as it ...
Influence of induction hardening residual stresses on rolling contact fatigue lifetime
(Elsevier, 2022-06)
[EN] Rolling contact fatigue is a unique mode of fatigue that components under cyclic contact loading experience. In this work, the impact of induction hardening residual stresses in rolling contact fatigue lifetime is ...
Implicit Subspace Iteration to Improve the Stability Analysis in Grinding Processes
(MDPI, 2020-11-19)
An alternative method is devised for calculating dynamic stability maps in cylindrical and centerless infeed grinding processes. The method is based on the application of the Floquet theorem by repeated time integrations. ...
Thermomechanical analysis of additively manufactured bimetallic tools for hot stamping
(Elsevier, 2020-09)
A comparison between a conventional AISI H13 hot stamping tool and a bimetallic tool consisting of an AISI 1045 core and a laser-deposited AISI H13 coating is performed. In order to analyze the performance of bimetallic ...
Influence of Axial Depth of Cut and Tool Position on Surface Quality and Chatter Appearance in Locally Supported Thin Floor Milling
(MDPI, 2022-01-19)
Thin floor machining is a challenging and demanding issue, due to vibrations that create poor surface quality. Several technologies have been developed to overcome this problem. Ad hoc fixtures for a given part geometry ...
