“…The advantages in the use of magnesium alloys are already known and reported in different publications [1][2][3][4][5][6], in particular for the automotive applications in which low density and high specific strength allow to reduce the weight, fuel consumption and consequently emissions of vehicles. In this context, the fabrication of tailor welded blanks (TWBs), obtained by joining two or more sheet metal blanks welded into a flat blank assembly, represents a further stage in the achievement of the above mentioned objectives.…”

The present investigation aims at studying the effect of the ratio between rotational speed and welding speed on the mechanical properties, such as the ultimate tensile strength and ductility, of friction stir welded joints in AZ 31 alloy sheets. To this purpose, FSW experiments were performed with different values of the ω/v ratio. The influence of the sheet thickness was also investigated. It was observed that an increase in the ω/v ratio produces an increase in the UTS and strain to failure up to a peak followed by a decrease, and that an increase in the sheet thickness leads to a reduction of the ω/v ratio at which the peak values are obtained.

MECHANIK NR 3/2015 ___________________________________________________________ 341Celem badań eksperymentalnych było określenie właściwości mechanicznych blachy nierdzewnej AMS5604 w temperaturze otoczenia (20°C) oraz w temperaturze podwyższonej w zakresie 50÷800 °C. Wyznaczono rów-nież wpływ prędkości odkształcenia na zmianę wartości podstawowych parametrów mechanicznych blachy. Próby statyczne rozciągania przeprowadzono w Laboratorium Badań Materiałów dla Przemysłu Lotniczego na maszynie wytrzymałościowej Instron 5982 (100kN). MECHANICAL PROPERTIES OF AMS5604 STAINLESS STEEL SHEETS AT ELEVATED TEMPERATUREThe aim of the experimental studies was to determine the mechanical properties of stainless steel AMS5604 at ambient and elevated temperature in the range of 50÷800 °C. The effect of strain rate on the change in the value of basic mechanical parameters of the sheet metal is also determined. The static tensile test is carried out at Research and Development Laboratory for Aerospace Materials using Instron 5982 100KN floor model universal testing system.

“…Light-weight engineering materials such as aluminum (Al) and magnesium (Mg) alloys are becoming crucial materials for weight-reduction-oriented industries due to environmental concerns, recycling properties, and energy conservation [1][2][3][4]. The restriction of the usage of these materials is related to the poor formability at room temperature because of alloying elements and atomic structures [2,5].…”

Development of Forming Temperature Curves for Warm Deep Drawing Process Under Non-isothermal Conditions

et al. 2015

View full text Add to dashboard Cite

Temperature is the main effective process parameter in the warm deep drawing (WDD) process to improve the formability of light-weight engineering materials, and this feature requires the accurate measurement and assessment of temperature for process stability. In this study, an evaluation of the WDD process was conducted according to the forming temperature curves (FTCs) characterized from work piece temperatures instead of tool temperatures, as usual. To achieve this goal, a special index material was developed to accurately obtain FTCs from the work piece material under closed and heated tool conditions. The differences of temperature on work piece material are required to define temperatures by curves. The characteristic behavior of these curves was investigated under non-isothermal WDD of AA 5754-O. In the experimentation stage, the process parameters, namely FTC, blank holder force and punch velocity, which assure successful deep drawability, were determined according to the failure-free cups by analyzing wrinkling and tearing conditions and minimum cup height parameters as output parameters. As the next step, optimum conditions were investigated by evaluating the cup volume and springback parameters. As a general conclusion, approximately 330 • C in the flange-die radius region and 100 • C in the cup wall-punch bottom region are the ideal optimum temperatures for the warm deep drawing process.
