Challenges of residual stress and part distortion in the civil airframe industry

Abstract: This paper aims to highlight challenges of residual stress and part distortion in civil airframe manufacture as this is a recurring expensive problem as significant costs have been spent to correct part distortion at various stages of the manufacturing life cycle. It is our long term commitment and aspirations to understand and if possible, eliminate part distortion in order to remain competitive. The paper briefly outlines current trends in civil aerospace industry and discussed the fundamental of residual stress and part distortion in high strength aluminium alloys. An insight into industrial state-of-the-art in managing residual stress and part distortion, learning obtained and long-term industrial aspirations are also discussed. Our recent participation in a European-funded collaborative project – COMPACT is also detailed here.

A historical overview of steel tempering parameters

Abstract: The results of the stress relieving and tempering processes are dependent on the temperature and time of the process, which may be correlated using a parameter such as Holloman's (Holloman-Jaffe) parameter or the Larsen-Miller parameter. These parameters are a measure of the thermal effect of the process on the metallurgical transformation of the steel during tempering. The processes that exhibit the same tempering parameter are expected to exhibit the same effect (such as hardness). However, these more traditional numerical expressions assume isothermal tempering processes which seldom exist in production tempering ovens due to the heat-up period prior to soaking

Corrosion resistance of Cr-Ni-Mo steel intended for urological stents

Abstract: This work presents the influence of the surface treatment and plastic strain of Cr-Ni-Mo stainless steel, intended for implants applied in urogenital surgery, on the steel's corrosion resistance. Tests were carried out in simulated urine at a temperature of 37 1C and pH = 66,4. In particular, pitting and crevice corrosion resistance tests were carried out. Furthermore, through the applied technique of stent implantation, the deformability of the passive layer was evaluated. The deformability tests of the passive layer were carried out with the use of a bend test followed by a corrosion test.

Modelling phase transformations and material properties critical to the prediction of distortion during the heat treatment of steels

Abstract: This paper describes the recent development of models in JMatPro for the calculation of phase transformations and material properties that are critical to the prediction of distortion during the heat treatment of steels. The success of these models is based on the accurate description of all the major phase transformations taking place, including the formation of ferrite, pearlite, bainite and martensite, as well as the calculation of the properties of the different phases formed during the heat treatment process. One advantage of the current models is that they can be applied to many types of steels, including medium- to high-alloy types. A wide range of properties such as density, thermal expansion coefficient, thermal conductivity, strength and hardness can be calculated, all as a function of time, temperature and cooling rate, even for an arbitrary cooling profile. The material data calculated from JMatPro have been exported directly to Finite Element (FE)/Finite Difference(FD)-based packages for forging/deformation simulation.
