Strong Ferritic – Steel Welds
There are many steels which are stronger than 2000 MPa, with toughness values exceeding 100 MPa m and which have been in commercial service for many decades. Examples include the marageing alloys and carbide–free bainitic steels. By contrast, welding consumables with a proof strength in excess of 1000 MPa are few and far between. This is because whereas wrought steels can be thermomechanically ...
متن کاملA New Standard for Radiographic Acceptance Criteria for Steel Castings
All components have performance limitations. These limitations are due to part design, part misuse, manufacturing practices and material characteristics. Non-destructive examination is specified by designers and users to ensure that the component purchased does not have features that would limit the component performance to less than the design requirement. Radiography can be used to detect int...
متن کاملTheory for Hydrogen Desorption in Ferritic Steel
After a concise review of the analytical models available for the interpretation of thermal desorption rates for hydrogen effusion from steel, a numerical method that incorporates the essence of local equilibrium and detrapping kinetics has been implemented to account for the real complexity of practical experiments. For example, the model permits the treatment of multiple kinds of traps, uses ...
متن کاملStrain-based fatigue data for Ti–6Al–4V ELI under fully-reversed and mean strain loads
This article presents the experimental data supporting the study to obtain the mean strain/stress effects on the fatigue behavior of Ti-6Al-4V ELI. A series of strain-controlled fatigue experiments on Ti-6Al-4V ELI were performed at four strain ratios (-1, -0.5, 0, and 0.5). Two types of data are included for each specimen. These are the hysteresis stress-strain responses for the cycle in a log...
متن کاملWorst Case Plastic Limit Analysis of Trusses under Uncertain Loads via Mixed 0-1 Programming
The paper presents a global optimization method to compute the minimum limit load factor of trusses subjected to unknown but bounded loads. We assume that the external forces consist of a part proportional to a load factor and a part that is uncertain around its nominal value. The worst-case limit load factor is introduced as the smallest limit load factor realized with some uncertain parameter...
