Abstract Experimental and clinical studies have highlighted that circulating tumor cell (CTC) with phenotypic hallmarks of epithelial-mesenchymal transition (EMT) plays a critical role in the metastatic recurrence solid malignancy. Here we retrospectively evaluated presence CTC its EMT phenotypes hepatocellular carcinoma (HCC) patients investigated their relevance. We optimized Canpatrol TM analysis system to enumerate classify 113 HCC before curative treatment 143 after treatment. The...
Low-cost and low-alloy dual-phase (DP) steel with a tensile strength (TS) above 1000 MPa high ductility is in great demand the automobile industry. An approach to using medium-carbon fibrous DP structure for developing such new has been proposed. The microstructure mechanical performance of obtained via partial reversion from martensite Fe-C-Mn-Si have investigated. TS as-quenched 1300 MPa, while total elongation less than 6%. was increased 13%, an acceptable loss by performing additional...
Aging treatment plays a significant role in altering the mechanical properties of superalloys; however, influences aging on performance Rene 41 alloy and its strengthening mechanisms remain unclear. In this study, effects microstructure forged were systematically investigated through experimental theoretical analyses. It was found that conditions have grain structure, γ′ characteristics, tensile alloy. The size secondary increased from 20 nm to 69 with elevated temperature prolonged time,...
Laboratory heating experiments with a varied holding time of GCr15 bearing steels at 1498 K were performed to study the transformation inclusions in solid during high temperature diffusion processes. Heating 1573 and 1648 also carried out effect these temperatures. Experimental results showed that transformed from Al2O3-CaO-(MgO) Al2O3-CaS-(MgO-CaO) when heat treatment was range due reactions between Al S steel matrix CaO inclusions. This is good agreement thermodynamic calculations....
The effect of Zr addition on the microstructure and impact toughness in coarse-grained heat-affected zone (CGHAZ) high-strength low-alloy steels subjected to 100 kJ cm-1 heat input was investigated. second- phase particles were mainly Al–Ti complex oxides (Ti,Nb)N precipitates Zr-free steel, whereas lots finer Zr–Al–Ti (Al,Ti,Nb)N formed Zr-bearing steel because addition. These effectively restricted austenite grain growth by pinning during welding thermal cycle, smaller more uniform prior...
The effects of a solution treatment on the microstructure and elevated mechanical properties forged Rene 41 superalloy were investigated. results indicate that temperature has significant influence γ′ structure properties. sub-solvus resulted in co-existence residual primary coarse precipitates fine secondary precipitates, while super-solvus treatments led to complete dissolution precipitation nano-sized spherical precipitate. tensile strength increased then decreased when from treatments....
Refining of the partially reverted globular austenite grain is great importance to obtain high mechanical property advanced strength steels and a new approach for such refining, pre-tempering initial martensite, proposed in this study. The results precipitation coarse alloying-elements partitioned cementite particles an Fe-2.5Mn-1.5Si-0.35C alloy. with Mn Si partitioning enhanced nucleation grains but suppressed its growth during continuous heating. enhancement restriction resulted...
Background: Radiofrequency ablation (RFA) is currently the most widely used thermal ablative technique for unresectable hepatic malignancies. However, microwave (MWA) also gaining popularity worldwide. With a cooled-tip electrode, MWA produces necrotic effects comparable to RFA without damaging soft tissues along electrode track. In this study, authors compared efficacy of these two modalities in treatment primary or secondary liver cancer.Materials and methods: Ultrasound-guided was...
The effects of heating rate on the formation acicular and globular austenite during reversion from martensite in Fe–2Mn–1.5Si–0.3C alloy have been investigated. It was found that a low enhanced austenite, while high favored austenite. growth γ accompanied by partitioning Mn Si, partitionless. DICTRA simulation revealed there transition mode to partitionless for with an increase temperature at rate. High rates promoted occurred temperatures, which made occur more easily. On other hand,...
Nonmetallic inclusions have a strong influence on the hydrogen-induced cracking (HIC) and sulfide stress (SSC) in pipeline steels, which should be well controlled to improve steel resistance HIC SSC. The effects of cooling rate formation nonmetallic been studied both experimentally thermodynamically. It was found that increasing increased number density decreased size inclusions, while inverse results were obtained by decreasing rate. Furthermore, as from 10 0.035 K/s, changed Al2O3-CaO...
In order to provide guidance for furthering the balance of strength and toughness AerMet 100 steel through tempering treatment, effects time on microstructure mechanical properties are investigated. The evolution, especially M2C precipitates austenite in tempered at 482 °C 1~20 h, was characterized, its influences were studied. tensile decreases gradually, yield increases first then decreases, fracture KIC gradually with an increasing time. matching is achieved by 5~7 h. Without considering...
