Originating from the early 1970s in Luleå, Sweden, and initially designed for agricultural industry, hot-stamped sheet steel has developed to become leading material a modern state-of-the-art lightweight structural automotive body engineering. This critical review provides detailed insight into origins, fundamental metallurgical principles, commercial growth, current legal stronghold on aluminising coatings latest technological developments. Comparisons other state-of–the-art ferrous...
Abstract Over the last four decades, numerous reports have appeared on physico‐chemical kinetics, especially crystallization based Avrami equation, ϕ = exp [− Kt n ] where is fraction of material unchanged at time t , K an overall rate constant and “ ” exponent indicative process mechanism. The usage equation has been limited to determination its temperature dependence. It shown that evaluation activation energy (E) using this erroneous since E are both influenced by although such would be...
In this note we study the average consensus algorithm in a distributed system of agents which are allowed to communicate according directed graph. Moreover, communication between connected is not perfect, but affected by some error, can be either random additive noise or produced quantization. We investigate effects these constraints on performance algorithms.
X-ray and electron diffraction studies of specific reaction intermediates, or intermediate analogues, have produced a consistent picture the structural mechanism light-driven proton pumping by bacteriorhodopsin. Of central importance within this is structure L-intermediate, which follows retinal all-trans to 13-cis photoisomerization step K-intermediate sets stage for primary transfer event from positively charged Schiff base negatively Asp-85. Here we report changes in bacteriorhodopsin...
The automotive industry is under increasing pressure to: (1) reduce the weight of vehicles and (2) improve crash performance. ‘Hot stamped’ mild carbon–manganese–boron steel 22MnB5 has become common place in body structure European vehicle over past decade. ultrahigh strength martensitic microstructure resulting from hot stamping (proof ∼1200 MPa ultimate tensile ∼1500 MPa) enables down gauging while not compromising However, with demands for yet higher final component so to enable further...
Elite athletes should have little concern about meeting recommended guidelines on physical activity. However, sedentary behaviour is considered a health risk independent of activity, and recognised in public advising against prolonged time. There has been very research athletes' activity outside elite sport.Given performance links, we investigated in-season post-training levels 28 professional footballers during the English Premiership season. Players volunteered to wear triaxial wrist...
Hot stamping was performed with seven novel boron steels, exhibiting various carbon contents and microalloy additions of Mo, V Ni compared to the standard 22MnB5 steel. The lower content 15MnB5 resulted in total elongation excess 11.0%. higher 38MnB5 ultimate tensile strength 2000 MPa. vanadium addition 1600 MPa combined were concluded give rise improved mechanical properties hot-stamped steel for automotive body engineering applications.
Hot stamping is performed with the 2000 MPa class 38MnB5 boron steel. Temperature evolution at critical regions of part geometry recorded by in situ thermocouple data logging part/die interface. Scanning Electron Microscopy, Energy Dispersive x‐ray Spectroscopy, X‐Ray Diffraction, and Vickers hardness testing are order to evaluate microstructural correlate observed temperature evolution. The microstructure predominantly martensitic flat geometry, exception < 1.5% retained austenite....
Modulated supraparticle structures are used to improve sandwich and competitive fluoroimmunoassays. The improved methods demonstrated on myoglobin, a key diagnostic protein for detection of heart damage. resulting method uses microliter volumes with bovine serum samples doped varying concentrations equine myoglobin. These immunoassays use micron-diameter iron oxide particles as solid phase antibody anchoring. Introduction magnetic field creates dipole moments the particles, which attracts...
Abstract A new concept based on differential scanning calorimetry (DSG) is introduced which enables us to make a rapid estimation of the thermal conductivity materials. This technique shown give reasonable agreement with literature data and offers unique advantages, e.g. short analysis time, no instrument modification, small radients across sample, spall sample size requirements, most importantly it can be applied polymer melts. Although our falls within range, difficult comment its accuracy...
Abstract A number of studies on the kinetics physicochemical processes are described. The methods used shown to be potentially useful for making time‐temperature predictions and optimizing process variables. Examples described include (1) long‐term prediction performance a plasticized polyvinyl chloride doped polyacetylenes; (2) polymerization monomer optimization time, temperature, initiator concentration variables; (3) analysis an order/disorder transition in thermochromic polymer; (4)...
