Effect of Tantalum on the Crack Resistance of NiCuBSi/65WC Composite Coatings [PDF]

Cailiao Baohu
Nickel-based composite coatings reinforced with tungsten carbide (WC) are widely used in surface engineering because of their high hardness and excellent wear resistance. Laser cladding，which is characterized by a high cooling rate，low dilution rate，high

Deformation characteristics and formability enhancement during ultrasonic-assisted multi-stage incremental sheet forming

Journal of Materials Research and Technology, 2022
Although the multi-stage incremental sheet forming strategy is beneficial for manufacturing complex geometrical shapes via objective transitional stages, the forming limit and geometric accuracy are highly dependent on intermediate shapes, which need ...

Stochastic simulation of woven composites forming [PDF]

, 1995
A stochastic forming simulation procedure is developed and implemented to investigate the effect of geometric variability in pre-impregnated woven textiles on manufacturing. Image analysis is used to characterise variability in tow directions and unit

Guideline for Forming Stiffened Panels by Using the Electromagnetic Forces

Metals, 2016
Electromagnetic forming (EMF), as a high-speed forming technology by applying the electromagnetic forces to manufacture sheet or tube metal parts, has many potential advantages, such as contact-free and resistance to buckling and springback.

Robot-Assisted Cold and Warm Incremental Sheet Forming of Aluminum Alloy 6061: A Comparative Study

Metals, 2023
Incremental sheet forming (ISF) requires no or partial dies for sheet metal fabrication and is widely used for small batch production. In this process, necking is either suppressed or delayed due to the localized nature of tool–sheet contact; hence, more

A simplified rate dependent model of forming and wrinkling of pre-impregnated woven composites [PDF]

, 2007
A simplified finite element model is developed and validated for the forming/ draping of pre-impregnated woven composites, incorporating the effects of wrinkling and strain rate dependence. The model development builds upon previous work on simulation

Experimental Evidence on Incremental Formed Polymer Sheets Using a Stair Toolpath Strategy

Journal of Manufacturing and Materials Processing
Incremental sheet forming represents a relatively recent technology, similar to the layered manufacturing principle of the rapid prototype approach; it is very suitable for small series production and guarantees cost-effectiveness because it does not ...

Induction Heating Validation of Dieless Single-Point Incremental Forming of AHSS

Journal of Manufacturing and Materials Processing, 2017
Advanced high-strength steel (AHSS) is subject to a high deformation in geometry due to spring-back and high forces during forming. Therefore, dieless single-point incremental forming supported by induction heating was introduced.

Process analysis and simulation of flat forging and forming steel tie rod U-shaped head preforms with super large

Journal of Hebei University of Science and Technology, 2021
In order to solve the problems of backward production technology, long processing cycle and low material utilization rate in traditional U-shaped steel tie rods, an integrated steel tie rod forming process was proposed.
