Powder of a nickel-based superalloy, RR1000, has been hot isostatically pressed (HIPped) at a supersolvus temperature and post-HIP heat treated to produce different microstructures. (PDF) Processingmicrostructureproperty relationships in ductile fracture behaviour of hot isostatically pressed CuttingSuryanarayanan et al. have with that of the Starck MoSi2 and the MoSi2/SiC shown that fracture toughness increases with relative composite, and this has compensated for the absenc~ of density in hot isostatically pressed (HIPed) MoSi2, and any toughening second phase in the monolithic R H P the value is around 4.2 MPa x/m for densities above MoSi2.

A New Microstructure-Sensitive Flow Stress Model for the High ductile fracture behaviour of hot isostatically pressed Cutting
This flow stress is developed to model the flow behavior of titanium alloys in machining at speed of higher than 5 m/s, characterized by extremely high strains (210 or higher), high strain rates (10 4 10 6 s 1 or higher), and high temperatures (6001300 C). The flow stress sensitivity to mechanical and material parameters is analyzed. Analysis of Hot Anisotropic Tensile Flow Stress and Strain ductile fracture behaviour of hot isostatically pressed CuttingThe two-stage work hardening behavior of Inconel 625 during hot deformation is well defined by Voce relationship with the correlation coefficient (> 99%). (iii) The fracture surfaces of Inconel 625 at various temperatures clearly indicate a ductilebrittle fracture with dimples being the main fracture feature. Ductile Fracture Behaviour of Hot Isostatically Pressed ductile fracture behaviour of hot isostatically pressed CuttingHerein we assess the differences in Charpy impact behavior between Hot Isostatically Pressed and forged Inconel 690 alloy over the temperature range of 300 C to - 196 C. The impact toughness of forged 690 exhibited a relatively small temperature dependence, with a maximum difference of ca. 40 J measured between 300 C and - 196 C, whereas the HIP'd alloy exhibited a difference of ductile fracture behaviour of hot isostatically pressed Cutting

In situ TEM Characterization of Microstructure Evolution and ductile fracture behaviour of hot isostatically pressed Cutting
Deformation and Fracture Behavior. To analyze the effect of the microstructure evolution on the mechanical properties, two specimens were cut from a single grain in as-printed IN718 within a few micrometers of each other and shaped into the push-to-pull samples as shown in Figure 1. Here, the tungsten probe was pushed against the sample at a ductile fracture behaviour of hot isostatically pressed Cutting Influence of Processing on the Microstructure and Mechanical ductile fracture behaviour of hot isostatically pressed Cuttingprocessing. After milling, the powders were cold isostatically pressed at 200 MPa and sintered in hydrogen at 1600C to reduce the impurity content (mainly oxygen). As a final step the sintered bars were further consolidated by hot isostatic pressing (HIP) for 4 h at 1500C and 200 MPa. Thereafter, residual porosity was less than 1% in all cases.

Influence of heat treatment on microstructure and tensile ductile fracture behaviour of hot isostatically pressed Cutting
Tensile fracture surfaces were examined using SEM. Discs for TEM examination were cut from the tensile-tested samples close to the fracture surfaces and normal to the tensile testing direction, followed by grinding to around 200 m thickness and then electro-polishing at 10 C and 25 V in 10% perchloric acid in methanol.
