Investigations on femtosecond laser micromachining of single crystal superalloys with and without plasma-sprayed thermal barrier coatings were conducted under laser fluences ranging from 0.1 J/cm up to 160 J/cm. Micromachining was carried out in air using a titanium:sapphire laser system ( = 780 nm) operating at a repetition rate of 1 kHz and delivering individual pulses of ~150 fs duration. Th...

Comparable investigation of pore-induced defects during in-phase (IP) and out-of-phase (OP) thermo-mechanical fatigue (TMF) were conducted on fourth-generation single crystal superalloy. It was discovered that recrystallizations deformation twins would take shape near micro-pores at IP OP cycling, respectively. High-resolution observation uncovered the increasing a/6〈112〉 twinning dislocations ...

PURPOSE In the present study, the three-dimensional power Doppler was used as a quantitative method to evaluate its reliability in detecting and assessing of gestational trophoblastic disease (GTD). METHODS 52 GTD patients who received diagnosis and treatment at the first affiliated hospitals of Xi'an Jiaotong University in China between 2011 and 2013 were evaluated using Voluson E8 (GE Medic...

The grapevine trunk disease (GTD) has been considered a real threat on grape production. This study aimed to identify the GTD causing agents in Palestinian orchards and evaluate efficacy of bacteria control under vitro conditions. Two fungal isolates; Fusarium solani isolate GR Neofusicoccum parvum GR3 were identified diagnosed using PCR BLASTn analysis. After that, five bacterial isolates test...

placental site trophoblastic tumor (pstt) is the rare variant of gestational trophoblastic diseases (gtd), which differs histologically and immunologically from gtd. diagnosis of pstt is often difficult and delayed. in most cases, diagnosis is not possible until the surgery is performed. the most therapeutic choice is hysterectomy and it is usually successful. here we report two cases of pstt.

The deformation mechanism correlations with individual grain orientation, overall texture, boundary characteristics, dislocation accumulation and evolutions were investigated during in-situ room temperature tensile testing of a nickel-based superalloy, Waspaloy. During testing, electron backscatter diffraction (EBSD) mappings, as well microscopy images acquired at increments displacement to obs...

hydromechanical deep drawing (hdd) is one of the most convenient processes in which a sheet metal is drawn against a counter pressure rather than a rigid die in conventional stampings. this process has been increasingly used to produce aerospace and automotive components. more recently, aerospace industry is demanding new materials with capability to produce high strength to weight ratio produc...
