“…The mechanical properties of metallic materials result from their internal defect population, i.e., from their microstructure. The superior properties of AHSS in comparison to conventional single-phase steels are a result of a much more complex microstructure that, firstly, contains multiple phases (Dual-Phase (DP) steels, Complex Phase steels [3,32,55,110,423] ), and secondly, has a staggered internal hierarchy (bainitic steels, [8,64,85,[424][425][426] martensitic steels [184,185,[427][428][429] ), and, third, can provide different deformation mechanisms (TRIP steels, [1,14,265,[430][431][432] TWIP steels [151,158,193,197,433,434] ).…”

“…Microstructure-based crystal plasticity (CP) models for AHSS rely on constitutive equations that describe the behavior of different phases based on their individual plastic deformation modes. [55,502] Besides, dislocation slip, these models might incorporate other plastic deformation modes, such as mechanical twinning and martensitic phase transformation. [453,501] As a result, these CP models are often very complex, and they contain a large number of constitutive parameters.…”

“…Therefore, recent progress in full-field crystal micromechanical modeling, taking the most important microstructure features into account, is presented to guide microstructure-based AHSS development. [31][32][33][34][35][36][37][38][39][40][41][42] Besides this focus on mechanisms some special topics such as steels with high Young's modulus, [43][44][45][46] additive manufacturing, [11,47,48] hydrogen embrittlement, [49][50][51][52][53] through-process modeling [54][55][56] , and machine learning applied to AHSS [57] are discussed as well but topics such as corrosion and welding are beyond the scope of this paper.…”

This is a viewpoint paper on recent progress in the understanding of the microstructure–property relations of advanced high-strength steels (AHSS). These alloys constitute a class of high-strength, formable steels that are designed mainly as sheet products for the transportation sector. AHSS have often very complex and hierarchical microstructures consisting of ferrite, austenite, bainite, or martensite matrix or of duplex or even multiphase mixtures of these constituents, sometimes enriched with precipitates. This complexity makes it challenging to establish reliable and mechanism-based microstructure–property relationships. A number of excellent studies already exist about the different types of AHSS (such as dual-phase steels, complex phase steels, transformation-induced plasticity steels, twinning-induced plasticity steels, bainitic steels, quenching and partitioning steels, press hardening steels, etc.) and several overviews appeared in which their engineering features related to mechanical properties and forming were discussed. This article reviews recent progress in the understanding of microstructures and alloy design in this field, placing particular attention on the deformation and strain hardening mechanisms of Mn-containing steels that utilize complex dislocation substructures, nanoscale precipitation patterns, deformation-driven transformation, and twinning effects. Recent developments on microalloyed nanoprecipitation hardened and press hardening steels are also reviewed. Besides providing a critical discussion of their microstructures and properties, vital features such as their resistance to hydrogen embrittlement and damage formation are also evaluated. We also present latest progress in advanced characterization and modeling techniques applied to AHSS. Finally, emerging topics such as machine learning, through-process simulation, and additive manufacturing of AHSS are discussed. The aim of this viewpoint is to identify similarities in the deformation and damage mechanisms among these various types of advanced steels and to use these observations for their further development and maturation.

“…Multi-scale methods [145][146][147] have been attempted in order to apply micro-scale models to macro-scale geometries but these require homogenisation techniques (e.g. varying the dimensions of laths but assuming that all laths are identical [140]) in order to reduce the complexity of the analyses, even though the macro-scale geometries are still relatively small compared to power plant components.…”

“…It should be noted that for the calibration of Hill's 1948 yield function, the material parameters for out of plane stress components were assumed to be same as the isotropic von Mises yield function, i.e. L = M = 1.5 [15,16]. In addition, the anisotropy coefficients of Yld2000-2D were calibrated using the normalized yield stress values (i.e.…”

The application of aluminum alloys is continuing to increase in automotive and aerospace industries. In this study, the stamping of a cross-shaped part, representing typical deep drawn automotive parts, was attempted with three different types of aluminum alloy sheets. To characterize the anisotropic properties of the material, uniaxial tensile tests were performed with ASTM standard dog-bone specimens cut from AA5052, AA5754 and AA6016 T4 alloy sheets. The stamping of the cross-shaped parts was conducted using a high capacity servo press with a servo-cushion system. Deformation strains developing in stamped parts were measured with the ARGUS system for comparison with finite element simulation results. Formed parts were also cut in two different directions using a water-jet machine, and thickness variations along the length of the cut section were measured. The measured surface strains and thickness distributions were compared with finite element simulations results obtained with LS-Dyna explicit code using the Yld2000-2D and Hill's 48 yield functions. Overall, experimental and numerical results correlated well, especially with the Yld2000-2D yield function, implying that this yield function is well suited for the modeling of the complex cross-shaped parts with aluminum alloys.
