Central damage is a serious defect in the solid products of cross wedge rolling. A combined
experimental and modelling approach was used to study the micro-mechanism of central …

Pores are often present in large aluminum ingots after casting. To ensure the mechanical
reliability of the final thick plates, these pores must be closed during the forming process, hot …

Innovations in many strategically important sectors, such as the aerospace, automotive,
energy and other industries, depend on making products from hard-to-deform materials. The …

A common feature of uniaxial high-temperature tension tests, and to a certain extent
compression tests, performed using a Gleeble thermomechanical testing system that …

As ductile damage has a severe impact on the performance of bearing steel-balls (BSB), it is
necessary to apply the ductile damage evolution model for predicting the distribution of …

In small deformation with hot rolling process, metals and alloys are subjected to complex
stresses, strain, strain-rate, stress flow, pressure, tensile triaxiality stress and compressive …

In this study, cracks formed in the edge side of Bi-S–based free-machining steel billets
during hot rolling were analyzed in detail, and their formation mechanisms were clarified in …

Effects of high-temperature hardness and oxidation on sticking phenomena occurring during
hot rolling of two STS 430J1L ferritic stainless steels were investigated in this study. Hot …

The reasons for the formation of surface cracks during the hot rolling of tool steels are not
well understood. However, we know that apart from the parameters of the thermo …

Seamless tube manufacturing utilises continuous cast cylindrical billets that, after piercing,
are rolled until a specified diameter, thickness and length are reached. The hollow part can …
