Development of Ternary Magnesium Alloys for Laser Powder Bed Fusion: Optimizing Oxide Layer Thickness

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

Dosage effect of superplasticizer on self-compacting concrete: correlation between rheology and strength

open access: yesJournal of Materials Research and Technology, 2019
This study presents the relationship between the rheology and the compressive strength of self-compacting concrete (SCC). The concrete mixes contained eight different dosages of superplasticizer.

Study on the Characteristics of Composite Recycled Aggregate Concrete Based on Box–Behnken Design Response Surface Model

open access: yesFractal and Fractional, 2023
This study investigates the influence of recycled fine aggregates (RFA) and waste concrete powder (WCP) on the compressive strength of concrete. The response surface methodology is employed, considering three factors: the content of WCP, the water–cement

Response surfaces for compressive strength of concrete

open access: yesConstruction and Building Materials, 2013
The aim of total quality management (TQM) is to offer satisfactorily high quality products to customers for providing increased productivity and decreased costs. Various methods are used for process improvement, development and optimization. In ready mixed concrete production, the number and the variations of effect parameters can be reduced using ...

From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming

open access: yesAdvanced Engineering Materials, EarlyView.
Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Non‐Destructive and Mechanical Characterization of the Bond Quality of Co‐Extruded Titanium‐Aluminum Profiles

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Analysis of Temperature and Stress Distribution on the Bond Properties of Hybrid Tailored Formed Components

open access: yesAdvanced Engineering Materials, EarlyView.
Hybrid materials enable high‐performance components but are challenging to process. This study explores an inductive heating concept with spray cooling for steel–aluminum specimens in a two‐step process including friction welding and cup backward extrusion.

Effect of Granule Strength on Compressed Tablet Strength.

open access: yesChemical and Pharmaceutical Bulletin, 1995
The effect of granule strength on the strength of a tablet compressed under a certain force was examined. Crushing strength and diametral compression tests were carried out to assess granule and tablet strength, respectively. When granules were weak, tablet strength increased with granule strength.

Applications of Gene Expression Programming and Regression Techniques for Estimating Compressive Strength of Bagasse Ash based Concrete

open access: yesCrystals, 2020
Compressive strength is one of the important property of concrete and depends on many factors. Most of the concrete compressive strength predictive models mainly rely on available literature data, which are too simple to consider all the contributing ...
