The Simulation of Post-Heat Treatment in Selective Laser Melting Additive Manufacturing
Integrating Materials and Manufacturing Innovation, 2021Post-heat treatment takes a key role for the enhancement of mechanical properties in selective laser melting (SLM) additive manufacturing (AM) of 6xxx series aluminum alloy. To understand the basic mechanism for changes of mechanical properties in the SLM process and the following post-heat treatment, the finite element model and the precipitate ...

Effect of post-heat treatment on microstructure and properties of EH47 steel CGHAZ
Materials Science and Technology, 2023To clarify the effect of post-heat treatment on the microstructure and mechanical properties of the coarse-grained heat-affected zone (CGHAZ) for EH47 steel, simulated CGHAZ specimens were subjected to post-heat treatment at 250°C for 1.0 h. The results showed that the microstructure of CGHAZ was composed of granular bainite (GB) and lath bainite (LB),

Post-heat treatment effect on the dielectric response of epoxy samples
2009 IEEE Conference on Electrical Insulation and Dielectric Phenomena, 2009In the present experiment, the dielectric response of various types of epoxies was investigated in the frequency and time domain. The samples consisted of nanostructured epoxy microcomposites and reference microcomposites. Water ingression at the fabrication step and/or at measuring time is known to affect the dielectric response of materials such as ...

Mechanical Properties of the TiAlSiN Coatings by Post Heat Treatments
2009In this study, TiAISiN coatings were deposited by cathodic arc evaporation from titanium, aluminum and silicon alloy targets in a reactive nitrogen atmosphere at substrate bias of −50 V. The as-deposited coatings were then subjected to post heat treatment at 400 °C in nitrogen ahnosphere.

Finite Difference Kinetics Modeling for Galvanized Steels with Post Heat Treatments
Advanced Materials Research, 2014Galvanized steels are widely used in construction, electronic, and automotive applications. By applying heat treatment after the hot-dip galvanizing process, zinc and iron in the galvanized coatings are interacted and series of zinc-iron intermetallic phases are developed. Correspondingly, the properties of galvanized steels may be enhanced.

Post-heat treatment of Nd:YAG laser welded high carbon steels
ICALEO '97: Proceedings of the Laser Materials Processing Conference, 1997Rapid cooling associated with laser welding can lead to poor component fatigue life. In general, the cooling rate of the welding process determines the weld quality and is dependent on: the weld geometry, laser parameters, beam profile at the workpiece and the material’s thermal and optical properties.

Interactive effect of surface densification and post-heat-treatment on aspen wood
Journal of Materials Processing Technology, 2010Abstract Surface densification technique can be used to enhance mechanical properties of low-density wood at a relative low temperature such as 145 °C. However, the final dimensions of densified wood products are not stable when exposed to cyclic weathering.

Accelerated detection of post‐heat‐treatment contamination in pasteurized double cream
International Journal of Dairy Technology, 1983A technique is described which enables a semi‐quantitative estimation of the extent of post‐heat‐treatment contamination of pasteurized double cream within 2 days. The method involves preincubation of the cream sample at 21° C for 25 h, after which Gram‐negative psychrotrophic bacteria are selectively counted (21° C/25 h incubation) on agar containing ...
