The Short Form of the Hagen Matrices Test (HMT-S; Heydasch et al. , 2013; see also Heydasch et al., 2020.) is an economic figural matrices test comprising six items that primarily measure induction, reasoning, and fluid intelligence according to the Cattell-Horn-Carroll (CHC) model of intelligence (Schneider & McGrew, 2012). It is a web-based test. The test is available in German, English and Spanish. The quality criteria have so far only been checked for the German version. Reliability is sufficient for group comparison Construct validity and criterion validity (correlations with school grades) are acceptable. Example items can be found online (https://ww2.unipark.de/uc/HOT_preview/?a=zis&b=&c=preview). The HMT-S can be requested via e-mail to the author for non-commercial research purposes., ZIS - The Collection of Items and Scales for the Social Sciences

The sequence of activation of deformation mechanisms in a near-β Ti-5Al-5Mo-5V-3Cr alloy quenched from the β-field is investigated as a function of strain during uniaxial compression at 0.001 s−1 up to ε = 0.041. Bulk in situ high energy synchrotron X-ray diffraction is applied to follow continuously the evolution of the microstructure of the alloy during deformation and is complemented with metallographic analysis. Stress induced β → α″ transformation takes place together with grain rotation of β upon reaching the yield stress of the alloy at ε = 0.021. During further loading, formation of β sub-grain cells is activated at ε ≥ 0.03. The stress-induced martensite forms with a strong texture of {200} α″ planes perpendicular to the compression direction.

The effects of intrinsic heat-treatment during selective laser melting of Ti-44.8Al-6Nb-1.0Mo-0.1B are studied and compared to extrinsic post-annealing. Phase evolution during heat-treatment of as-built samples studied by in situ synchrotron radiation diffraction showed pronounced intensity changes and peak shifts below the eutectoid temperature, which are explained by stabilization of α2 as well as transformations to γ and β/βο. These observations contrast the marginal intensity changes found for the microstructure thermodynamically stabilized by hot isostatic pressing. The intrinsic heat-treatment of the as-built state leads to graded microstructures characterized by an increase of globular γ and β/βο at the α2/γ colony boundaries.
